Each car and tire may handle best with different tire pressures and even this can vary depending on track conditions - temperature, humidity, etc. The best suggestion I received was to go out with standard pressure and compare this with pressure at end of run - to determine the increase. Readjust for the second run, making certain that expected heated pressure does not exceed maximum on tire. You also may want to fiddle with the pressure (as noted above) to alter the handling - more understeer or oversteer, etc. Finally, you probably also want to test the torque of the lug nuts on each wheeel prior to each session.

 

Right on Robert. I hired a pro driver for my forst time and he was very careful about inspection of the tires, et. al. He was particularly interested in how the wear appeared on the outside/edge radius of the tire. Only issues I had with him were 1. He races vettes and 2. He is sponsered by Kuhmo tires and I was on MPSCs (Just joking).

 

hiring a pro driver would be nice but not NEEDED at the beginning stages. you have, at your disposal, many pca regional instructors for the price of your pca track entry fee and pca membership. it's good to start out with porsche folk 'cause they know how a 911 should behave, not some vette guy. you will be drilled on taking the porsche line/dogma "slow in, fast out", "late apex" to be safe. they will make you concentrate on being smooth and consistent. once you achieve this then push it a little more. little steps. a pro coach might try to push you too much and emphasize on time not smoothness consistencey.

if you are trying to squeeze out tenths per lap and need a new perspective then that is the time to go for a pro coach. any credible large club NASA, PCA, POC, SCCA etc... will have instructors. avoid test/lapping days that don't have any instruction.

 

first of all... HAVE FUN ! Be relax, smooth, and take your time.
Don't be agressive.
Go out with a instructor. He will show you the Line.... the good line.
All the advice you received about inspection, tire pressure, etc... are very good.
You must run window open and A/C close.
Start with street tire. Better for learning.
secret: Late apex. Slow in, fast out!!!

TT is very hard on brake. high temp. liquid fluid is a good idea.

check for the web site of the track. you will have an idea of the line.
and remember... Have fun!

 

GOSH DARN IT I CAN WAIT... i wish the track day was already here... few more days though... ALL the input so far is GREAT...

I persume the idea of late entry is to decrease the chances of understeer... as for tires... The turbo i am running has some Conti's on them... Not a big fan of the Conti's but i am sure it will be fun non the less... If anyone is interested and lives in the LA area and wants to attend PM me and i give you the heads up...

THANKS YALL...

 

A suggestion, try to keep your excitement under control, at least at the beginning of the day. You will have much smoother and safer laps if you remain calm and remember to breathe. It is very easy to get caught up in the red mist - I am a prime example. Your car is fantastic and will provide you with the opportunity to drive with almost every other non-race prepared car. I personally used to love to try to keep up with/pass GT-3's, but remembering that there were limits, both physical and my skills.

Also, the issue of windows down, etc., different clubs have different rules, e.g. you can't have your window completely open if you have a net and therefore passing signals or wave-byes must be given inside the car. Also, I now find it very amusing that while my PCA region required top up, the F car rules require me to drive with my top down.

Enjoy.

 

Would you say that understeer is more pronounced on a TT than a C2 ? And are you refering to turn in understeer or rear-squat-induced understeer under acceleration ?
I've had a lot of trouble getting used to the C2 understeer on the road, I find it much better on the track. Wondering if I'll regret the move to a TT.

 

Totally going to take it slow for at least 3 laps...each time giving it a little more in the turn seeing how well the car can handle it... From there i am just going to just keep pushing until i feel i am at a decent speed for excitement and safety...Mainly cause the car i am using isnt my car...not taking the Turbo S taking an 04 X50 coupe... just to see how i like it as a track car..

One question i havent really heard about is PSM... Is the car more trackable with it off or with it on... I am asking this cause in some instances i might want to let the rear end swing out a little and so fourth... I know for the first few laps i push it i will keep it on...but i want to know will i shread a few seconds if i turn it off and really give the car a good hussle through...

 

IMHO there is NO reason to really ever turn off the PSM especially your first time with a TT on the track!? and its not yours!!?? and you want to "let the rear end swing out!!!!! ah oh! that better not be happening your first time out!! LOL have fun!! and no you will not be any faster with the psm off. and shedding seconds is a huge deal on a race track lap!!
safe, smooth, fast driving with the PSM on you will not feel the PSM unless you need it!!

 

just to let you know i am more or likely going to buy this car... so i am not going to abuse it...when i mean let the rear end swing a little... i mean let it over steer a little in a tight turn or two... also i am paying a good deal to take this car...so i should give it a go especially if i want to use it as a track car... I gotta see what it can do in the stock trim.

 

I understand but be careful, it still takes alot to get the *** of this car to kick out (of course I have 12 inch rear wheels with cup tires) in street form it may be a little easier. let us know what you think, I am truely addicted to tracking this car!!! You sound like you will be also, then we can talk on what to do next!!!

 

well i have had some fun around my house getting the rear end out in a control..Not totally sideways mind you but a you can feel it in ur butt that the car is off a little... but i have always done it with PSM off... well i guess we will have to see...

 

Totally agree here !
